Initially Dortmund was thought to have difficulty winning the match against Heidenheim who were in their best form, but Dortmund was able to dominate this match and finally won this match easily.
Heidenheim is not as strong as it looks, they started the season with two wins and a pretty good goal productivity, but Dortmund with all the problems and was doubted by many people was able to show their best performance.
I highlight Dortmund's performance with their new coach at the beginning of this season, I think Nuri Şahin was quite successful in making stability in Dortmund's performance at the beginning of this season and he only needs to add progress to be able to make the team better, this is a good start for Nuri Şahin.
Study found that a coach experience and leadership style can greatly affect how well team plays. Sahin used to play for Dortmund and was captain so he knows the team well. This helped him make the team stronger.
Dortmund now controls the ball more 55.6% vs 44.4% last season and scores more goals 13 goals in 5 matches. This shows that Sahin tactics work. Heidenheim started the season well but Dortmund win showed their weaknesses. It will be interesting to see if Sahin can keep improving team and lead them to even more success.
